          Optionnally also plot associated :class:`~tofu.geom.Ves` and Struct
          The plot can also include:
              - special points
              - the unit directing vector
  
          Parameters
          ----------
          Lax :       list / plt.Axes
              The axes for plotting (list of 2 axes if Proj='All')
              If None a new figure with new axes is created
          Proj :      str
              Flag specifying the kind of projection:
                  - 'Cross' : cross-section
                  - 'Hor' : horizontal
                  - 'All' : both cross-section and horizontal (on 2 axes)
                  - '3d' : a (matplotlib) 3d plot
          element :   str
              Flag specifying which elements to plot
              Each capital letter corresponds to an element:
                  * 'L': LOS
                  * 'D': Starting point of the LOS
                  * 'I': Input point (i.e.: where the LOS enters the Vessel)
                  * 'O': Output point (i.e.: where the LOS exits the Vessel)
                  * 'R': Point of minimal major radius R (only if Ves.Type='Tor')
                  * 'P': Point of used for impact parameter (i.e.: with minimal
                          distance to reference point Sino_RefPt)
          Lplot :     str
              Flag specifying the length to plot:
                  - 'Tot': total length, from starting point (D) to output point
                  - 'In' : only the in-vessel fraction (from input to output)
          element_config : str
              Fed to self.config.plot()
          Leg :       str
              Legend, if Leg='' the LOS name is used
          dL :     dict / None
              Dictionary of properties for plotting the lines
              Fed to plt.Axes.plot(), set to default if None
          dPtD :      dict
              Dictionary of properties for plotting point 'D'
          dPtI :      dict
              Dictionary of properties for plotting point 'I'
          dPtO :      dict
              Dictionary of properties for plotting point 'O'
          dPtR :      dict
              Dictionary of properties for plotting point 'R'
          dPtP :      dict
              Dictionary of properties for plotting point 'P'
          dLeg :      dict or None
              Dictionary of properties for plotting the legend
              Fed to plt.legend(), the legend is not plotted if None
          draw :      bool
              Flag indicating whether fig.canvas.draw() shall be called
          a4 :        bool
              Flag indicating whether to plot the figure in a4 dimensions
          Test :      bool
          a4 :        bool
